Referring to FIG. 1 , the disclosure provides an e-liquid storage bin assembly 100. The e-liquid storage bin assembly includes an e-liquid storage bottle 110 and an e-liquid separation bin assembly 120. The e-liquid separation bin assembly 120 includes an e-liquid separation bin 123 and an e-liquid separation bin sealing ring 122. The e-liquid storage bottle 110 includes a housing 114 in which a pipeline 112 with a first passage 1121 is arranged. One end of the first passage 1121 is located in the housing 114, and the other end of the first passage 1121 is communicated with the outside of the housing 114. The e-liquid separation bin 123 is connected to the housing 114 and has a first accommodating cavity 1231 inside. The e-liquid separation bin 123 is provided with a first e-liquid penetration hole 124 which is communicated with the first accommodating cavity 1231. The pipeline 112 and the e-liquid separation bin 123 are arranged oppositely. The e-liquid separation bin sealing ring 122 is arranged around the pipeline and the e-liquid separation bin 123 and seal the first e-liquid penetration hole 124. The e-liquid separation bin sealing ring 122 is further provided with a through hole 1251 through which the first passage 1121 and the first accommodating cavity 1231 are communicated. The e-liquid separation bin seal ring 122 is movable relative to the pipeline 112 and the e-liquid separation bin 123 to open the first e-liquid penetration hole 124.

The e-liquid separation bin assembly further includes a fixing ring 121. The fixing ring 121 is arranged around the e-liquid separation bin sealing ring 122 and configured to fix the e-liquid separation bin sealing ring 122, thereby preventing the e-liquid separation bin sealing ring 122 from deforming.

As shown in FIG. 6 , the e-liquid separation bin sealing ring 122 is further provided with a plurality of recesses 1227 evenly distributed along the circumference of the e-liquid separation bin sealing ring 122. Arrangement of the recesses 1227, which can be tightly attached with the fixing ring 121, can reduce the materials for the e-liquid separation bin sealing ring 122, thereby saving the cost.

An e-liquid storage space 111 is defined by an inner wall of the housing 114, an outer wall of the pipeline 112 and the e-liquid separation bin sealing ring 122 to store e-liquid. Therefore, when the e-liquid storage bin assembly 100 is used in conjunction with the atomization core assembly 200, the atomization core assembly 200 can be placed in the first accommodating cavity 1231 of the e-liquid separation bin 123, and the e-liquid separation bin sealing ring 122 can be pushed to open the first e-liquid penetration hole 124, such that the e-liquid in the e-liquid storage space 111 enters the first accommodating cavity 1231 through the first e-liquid penetration hole 124. The first accommodating cavity 1231, the through hole 1251 formed in the e-liquid separation bin sealing ring 122, and the pipeline 112 form a passage communicating the e-liquid separation bin 123 and the outside of the housing 114, and the e-liquid, when atomized, is discharged from one end of the pipeline 112 communicated with the outside of the housing 114 for the user to inhale.

For example, as shown in FIGS. 1, 3, and 4 , the e-liquid separation bin sealing ring 122 covers the first e-liquid penetration hole 124 and confines the e-liquid in the e-liquid storage space 111. When the e-liquid separation bin sealing ring 122 moves, relative to the pipeline 112 and the e-liquid separation bin 123, to a position where the first e-liquid penetration hole 124 is fully or partially opened and the e-liquid storage space 111 is communicated with the first e-liquid penetration hole 124, the e-liquid can flow into the first accommodating cavity 1231 through the first e-liquid penetration hole 124.

The e-liquid separation bin sealing ring 122 further includes a first sealing portion 1223 and a second sealing portion 1224. The first sealing portion 1223 is arranged around a periphery of the pipeline 112 and is movable relative to the pipeline 112. A limiting groove 1221 is defined between the second sealing portion 1224 and a periphery of the first sealing portion 1223. The second sealing portion 1224 is arranged around the e-liquid separation bin 123 and seal the first e-liquid penetration hole 124. When the e-liquid storage bin assembly 100 is in an unused state, the second sealing portion 1224 is configured to block the e-liquid and prevent the e-liquid in the e-liquid storage bottle 110 from flowing out due to the communication between the e-liquid storage space 111 and the first e-liquid penetration hole 124. The first sealing portion 1223 is circumferentially provided with protrusions 1222 which abut against the outer wall of the pipeline 112. The protrusions 1222 are configured to block the e-liquid, and prevent the e-liquid from entering the pipeline 112 and blocking the pipeline 112 such that the smoke cannot flow out through the pipeline 112 smoothly, resulting in extremely poor user experience during use. A plurality of protrusions 1222 may be arranged side by side or spaced apart on the first sealing portion 1223 to enhance the sealing reliability. It should be noted that after the first sealing portion 1223 is arranged around the pipeline 112, the first sealing portion 1223 will be deformed to a certain extent in the circumferential direction. That is, there is a certain amount of pressure between the protrusions 1222 and the outer wall of the pipeline 112. When there is a tendency of relative movement between the protrusions and the pipeline, a certain frictional force will be generated to hinder the relative movement between the protrusions 1222 and the outer wall of the pipeline 112. Therefore, the relative stability of the sealing ring 122 of the e-liquid separation bin 123 in position can be ensured, and e-liquid leakage caused by the movement of the e-liquid separation bin 123 due to the inclination of the e-liquid storage bin assembly 100 during transportation is avoided.

The first sealing portion 1223 is further provided with a first abutting portion 1225. A distance between the first abutting portion 1225 and an end of the first passage 112 facing the e-liquid separation bin 123 is greater than a distance between an end 1226 of the second sealing portion and a farthest point of the first e-liquid penetration hole 124. That is, it can be ensured that when the first abutting portion 1225 abuts against the end of the pipeline 112, the second sealing portion 1224 will not block or partially block the first e-liquid penetration hole 124, so that the e-liquid can flow into the first e-liquid penetration hole 124 from the e-liquid storage space 111 smoothly. The e-liquid separation bin sealing ring 122 can slide relative to the first passage 1121 and the e-liquid separation bin 123, so that the first abutting portion 1225 abuts against the end of the pipeline 112. The first abutting portion 1225 is stably abutted against the end of the pipeline 112, such that the first e-liquid penetration hole 124 can be continuously communicated with the e-liquid storage space 111, thereby ensuring a stable flow of the e-liquid into the first accommodating cavity 1231.

Referring to FIG. 1 , in some embodiments of the disclosure, the e-liquid storage bin assembly 100 further includes a cartridge sealing ring 125. The e-liquid separation bin 123 compresses the cartridge sealing ring 125, such that the cartridge sealing ring 125 is deformed radially to abut against the inner wall of the e-liquid storage bottle 110 and the outer wall of the e-liquid separation bin 123 respectively. The cartridge sealing ring 125 can prevent the e-liquid from flowing out via a gap between the e-liquid separation bin 123 and the e-liquid storage bottle 110. It can be understood that a plurality of cartridge sealing rings 125 may be provided as required to enhance the sealing reliability.

Referring to FIG. 1 , a connecting portion for connecting with the atomization core assembly 200 is arranged on the inner wall of the housing 114. In the e-liquid storage bin assembly 100, the e-liquid storage space 111 is defined by the inner wall of the housing 114, the outer wall of the pipeline 112 and the e-liquid separation bin sealing ring 122 to store e-liquid. Therefore, the e-liquid storage bin assembly 100 can be separately produced, packaged, transported and sold. The e-liquid storage bin assembly 100 can be used in conjunction with the atomization core assembly 200 to generate smoke for people to inhale.

Referring to FIGS. 3 to 4 , the disclosure further provides an atomizer 1000, which includes the e-liquid storage bin assembly 100 according to the embodiment in the above first aspect, and an atomization core assembly 200. The atomization core assembly 200 is detachably connected with the e-liquid storage bin assembly 100, and includes an e-liquid separation pipe 210. The e-liquid separation pipe 210 has a second accommodating cavity 211 inside. The e-liquid separation pipe 210 is provided with a second e-liquid penetration hole 240 which is communicated with the second accommodating cavity 211. In the atomization core assembly 200 connected to the e-liquid storage bin assembly 100, the e-liquid separation pipe 210 is located in the second accommodating cavity 211 of the e-liquid separation bin 123. The second e-liquid penetration hole 240 can be communicated with the first e-liquid penetration hole 124. The first e-liquid penetration hole 124 is larger than the second e-liquid penetration hole 240, thereby preventing the first e-liquid penetration hole 124 from blocking a part of the second e-liquid penetration hole 240 due to manufacturing and assembly errors, which affects an e-liquid penetration effect.

In some embodiments of the disclosure, as shown in FIGS. 3 to 4 , the atomization core assembly 200 can push the sealing ring 122 of the e-liquid separation bin 123 to slide toward the pipeline 112, so that the e-liquid storage space 111 is communicated with the first e-liquid penetration hole 124. The second e-liquid penetration hole 240 is able to directly face and communicate with the first e-liquid penetration hole 124 by rotation of the atomization core assembly 200 relative to the e-liquid storage bin assembly 100. When the atomization core assembly 200 pushes the sealing ring 122 of the e-liquid separation bin 123 until the first abutting portion 1225 abuts against the end surface of the pipeline 112, the second e-liquid penetration hole 240 and the first e-liquid penetration hole 124 are in a state of misalignment, such that the e-liquid cannot enter the atomization core assembly 200. After the atomization core assembly 200 rotates relative to the e-liquid storage bin assembly 100, the first e-liquid penetration hole 124 and the second e-liquid penetration hole 240 are aligned so that the e-liquid enters the atomization core assembly 200.

As an alternative to the above solution, the atomization core assembly 200 is plug-connected to the e-liquid separation bin assembly 120, the e-liquid separation pipe 210 can be inserted into the first accommodating cavity 1231, and push the e-liquid separation bin sealing ring 122 to slide away from the e-liquid separation bin 123 to open the first e-liquid penetration hole 124, and the second e-liquid penetration hole 240 is communicated with the first e-liquid penetration hole 124. That is, after the first e-liquid penetration hole 124 and the second e-liquid penetration hole 240 are aligned, the atomization core assembly 200 is then combined with the e-liquid separation bin assembly 120.

In some embodiments of the disclosure, as shown in FIGS. 2 to 6 , the e-liquid storage bin assembly 100 is provided with a sliding groove 113, the atomization core assembly 200 is provided with a buckle 271, and the buckle 271 can slide along the sliding groove 113 and is configured to fix the atomization core assembly 200 to the e-liquid storage bin assembly 100. Since the sliding groove 113 is provided with a protrusion and the buckle is provided with a recess corresponding to the protrusion in shape, when the buckle slides along the sliding groove 113 until the protrusion is clamped with the recess, the atomization core assembly 200 and the e-liquid storage bin assembly 100 are both in correct installation positions. At this time, the second e-liquid penetration hole 240 is directly faced and communicated with the first e-liquid penetration hole 124, such that the e-liquid passes through the first e-liquid penetration hole 124 and the second penetration hole 240 from the e-liquid storage space 111 and enters the atomizer 1000. It can be understood that the same purpose can also be achieved in the case that the e-liquid storage bin assembly 100 is provided with a buckle, and the atomization core assembly 200 is provided with a sliding groove 113. It should be noted that when the e-liquid is used up or in other cases where the e-liquid storage bin assembly 100 needs to be replaced, by rotating and pulling out the atomization core assembly 200 in a direction opposite to the installation direction, and the atomization core assembly 200 can be then separated from the e-liquid storage bin assembly 100. Since the atomization core assembly 200 is relatively expensive, and the e-liquid storage bin assembly 100 is relatively cheap, the atomization core assembly 200 can be combined with a new e-liquid storage bin assembly 100 to form a new atomizer 1000, thereby avoiding the waste. In addition, because the new e-liquid storage bin assembly 100 is installed only after the e-liquid in the e-liquid storage space 111 is used up, there is no need to worry about e-liquid leakage in the e-liquid storage bin assembly 100 after the atomization core assembly 200 is separated from the e-liquid storage bin assembly 100.

In some embodiments of the disclosure, as shown in FIG. 8 , the atomization core assembly 200 further includes a core pipe 220, an e-liquid storage core 230, a heating wire 250, a rubber ring 260, a cartridge holder 270, and an electrode 280. The e-liquid separation pipe 210 is arranged around the core pipe 220. The core pipe 220 is fixedly connected to the cartridge holder 270. The buckle 271 is arranged in the cartridge holder 270. The e-liquid storage core 230 is arranged in the core pipe 220. The heating wire 250 is arranged in the e-liquid storage core 230 and configured to heat e-liquid to generate smoke. The heating wire 250 is in conductive contact with the electrode 280. The rubber ring 260 is installed between the core pipe 220 and the e-liquid separation pipe 210 to prevent the leakage of e-liquid. The e-liquid flows into the atomization core assembly 200 from the second e-liquid penetration hole 240 formed in the e-liquid separation pipe 210, and is absorbed by the e-liquid storage core 230. When the e-liquid storage core 230 is fully infiltrated by the e-liquid, the electrode 280 is energized to heat the heating wire 250. The temperature of the heating wire 250 rises to atomize the e-liquid, and the atomized e-liquid flows out from the pipeline 112 for the user to inhale. It can be understood that the e-liquid storage core 230 may be made of materials with good e-liquid absorption properties such as cotton and polyester.

The disclosure further provides an electronic cigarette (not shown in the drawings), which includes the atomizer 1000 provided in the embodiment of the second aspect, and a battery assembly (not shown in the drawings). The atomizer 1000 is detachably connected (generally, in a magnetic connection) to the battery assembly. The battery assembly can be connected to the atomizer 1000 while supplying power to the electrode 280. The electronic cigarette is further provided with an indicator light for displaying an electric capacity, so as to remind the user to charge it in time when the electric capacity is low.

However, the disclosure is not limited to the above-mentioned embodiments, and various changes can be made without departing from the purpose of the disclosure within the scope of knowledge possessed by those of ordinary skill in the art.
